Tumbling energy costs kept US consumer inflation in check last month, blunting upward pressures in prices for housing and medical care, according to government data released today. 

As a result, the consumer price index held steady in September, pausing following recent gains despite historically low unemployment and rising wages. 

The latest figures were unlikely to shift views among US Federal Reserve policymakers, many of whom fear the world's largest economy is increasingly vulnerable. 

The Fed later this month is expected to cut interest rates for the third time in 2019.

Compared to August, the consumer price index, which tracks costs for household goods and services, was flat as energy prices continued their recent decline, falling another 1.4%, including a 2.4% drop in gasoline.

Over the last 12 months, CPI rose 1.7%, the same as in August, as energy prices are down 4.5%.

Even when volatile food and fuel prices are stripped out, core CPI rose just 0.1% for the month, below economists' expectations.

Compared to September of last year, the core measure was up 2.4%, also the same as August - which had been the biggest increase since July 2018 and a level not exceeded in a decade. 

That measure was held down by a steep 1.6% drop in used car prices, but economists said they are expected to rebound, a repeat of what happened at this time last year.

In addition to shelter and medical care, costs for car insurance and household furnishings rose, along with education and air fares.
